フットサル競技における“チーム重心”を用いたゲーム分析に關する硏究 = A Study of Game Analysis by Using The Parameter "The Team Center of Gravity" in The Futsul Game

다국어 초록 (Multilingual Abstract)

In the research regarding the analysis of football game, the various ways are used. And the football game is very mobile and difficult to evaluate the movement of the whole team objectively. However, the futsul game is played with 5 players, so we can conceive that the analysis of the futsal game is easier in comparison with the football game.
The purpose of this study is the analysis of the futsul game, by using the new parameter called 'the team cetner of gravity' that is calculated by DLT method. Furthermore, we examine the usefulness of this parameter.
Setting two videl cameras (SONY CCD-TR2000), each one covering an entire pitch, recorded one of THE FUTSAL JAPAN CAP MATCHES. It captured every l/3sec frame from the recorded tape, and coordinated positions of all player movements and ball using application software (MPJAPAN VM95). The coordinated position's data are treated with original application software.
After analyzing the data, we found the following:
1) We found that the distance between the center of gravity of both teams was modified right away even if it spread temporarily. It was conceivable that the defense side was being about to correspond to the attack side of the enemy continually. As the distance between the center of gravity of both teams becomes short, the game becomes intense in offense and defense.
2) It proved that the distance from the center of gravity to each player spread and the player was more activity during offense and that the player concentrated in some degree and controlled their minimum movement during defense.
3) From the result of this study, the usefulness was suggested to analyze the futsal game by using the parameter called 'the team center of gravity', when we did it objectively in the futsul game.
